Expand description

Extension methods for constructing std::time::Duration with numbers.

§Note

This trait is not implemented for the Duration, for extension methods operating on a Duration, see crate::time::DurationExt for more information.

§Warning

Unlike the DurationNumExt, this trait’s method returns an Option<Duration>. Numbers that may be too large to be represented like num::BigInt or may be negative like signed integers will implement this trait.

Required Methods§

fn seconds(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.seconds(), Some(Duration::from_secs(10u64)));
assert!(u128::MAX.seconds().is_none());

fn milliseconds(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;


assert_eq!(10u128.milliseconds(), Some(Duration::from_millis(10u64)));
assert!(u128::MAX.milliseconds().is_none());

fn microseconds(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.microseconds(), Some(Duration::from_micros(10u64)));
assert!(u128::MAX.microseconds().is_none());

fn nanoseconds(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.nanoseconds(), Some(Duration::from_nanos(10u64)));
assert!(u128::MAX.nanoseconds().is_none());

fn minutes(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.minutes(), Some(Duration::from_secs(10u64 * 60)));

fn hours(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.hours(), Some(Duration::from_secs(10u64 * 60 * 60)));

fn days(&self) -> Option<Duration>

Create a Duration, using the postfix syntax.

§Example

use rs_std_ext::time::DurationNumExtFallible;
use std::time::Duration;

assert_eq!(10u128.days(), Some(Duration::from_secs(10u64 * 60 * 60 * 24)));
